5 About Xmanager Xmanager is a powerful, convenient PC X server software package that operates in the Windows environment. Users can bring the UNIX/Linux desktop to their Windows PC via Xmanager. Additionally, the X application can be safely executed through SSH (secure shell) even when a user s PC is inside a private network or there is a firewall in between a user PC and remote server. Xmanager offers diverse functions, such as setting multiple servers, multi-visual, multimonitor, multiple user settings, multiple XDMCP sessions, and SSH security reinforcement. Xmanager provides a variety of premium options for advanced users and a simple user interface for first-time users. Xmanager comprises Xmanager, Xconfig, Xbrowser, Xstart and several other utilities. Xmanager is an X server program for PC. X client, a graphic remote UNIX/Linux application, can show a screen in Windows through Xmanager. Xstart and Xbrowser run Xmanager when running a remote X application or when bringing the whole GUI desktop screen of a remote host. Xconfig creates and manages Xmanager server profile. Xmanager profile sets various Xmanager options, such as window modes, font catalogs, and colors. Xbrowser finds a remote UNIX/Linux host and enables connection with the remote host using the XDMCP protocol. Xbrowser compositely manages Xstart, Xshell, and Xftp sessions in addition to XDMCP sessions. Users can run several sessions simultaneously and create shortcut icons for each host. Xstart enables the execution of a remote X application on a user s PC. When connecting with a remote host, it supports SSH, TELNET, RLOGIN, REXEC, RSH and LOCAL protocols. A remote host command can be conveneintly executed, on a user s Windows PC via Xstart. About Xmanager 3

9 Start Xmanager provides Xbrowser and Xstart, two basic tools for accessing a remote UNIX/Linux host. Xbrowser can be conveniently used by most users as it enables to bring the entire remote desktop via XDMCP (X display manager control protocol). Xstart is simpler and quicker than an XDMCP connection, as it is a method to run a single remote X application. When Xmanager is successfully installed, Xstart and Xbrowser programs can be found in the Xmanager folder on the desktop. Run Xmanager - Passive in the Xmanager installation folder for Xmanager to enter standby mode for X application connection. Users can then run a remote X application using Xstart or other tools. Run Xmanager - Broadcast in the Xmanager installation folder and Xmanager broadcasts a XDMCP Query message through network. Hosts that respond to the query message are listed in the Chooser window. A host can be selected from the list and a connection to it can be made. Start 7

10 Start with Xbrowser To use Xbrowser, set a remote UNIX/Linux host to support XDMCP service for a remote X server. In general, dtlogin, kdm, gdm, or xdm must be running on the host. For details about XDMCP service setting, see manual for the UNIX/Linux concerned. 1. Open Xmanager or Xmanager Enterprise folder on your desktop. Fig. 1: Xmanager Enterprise Folder 2. Run Xbrowser. Xbrowser automatically finds all UNIX/Linux hosts in the local network. If the UNIX/Linux host to access is on a different network than the user s PC, register the UNIX/Linux host IP address or broadcast address in the Options dialog box. For setting details, see Automatic XDMCP Session. If a UNIX/Linux host is not displayed in the Xbrowser window, it means that the host is not prepared for an XDMCP connection. 8 Start

11 Fig. 2: Xbrowser main window 3. Double-click a host to connect to. Graphic login screen opens. If graphic login screen is not displayed, it is possible there is a firewall between the user s PC and a remote host. Start 9

12 Fig. 3: XDMCP login screen 4. Log in to host by entering the account name and password. Remote desktop opens. There may be a problem in the user account login shell script if the remote desktop is not displayed after entering account and password. 10 Start

13 Fig. 4: UNIX desktop executed in Windows If you experience problems using Xbrowser, visit the customer support page in the following address: Information about the XDMCP settings in UNIX/Linux server and related tips can be found on the customer support page. Start with Xstart Xstart helps run a remote X application. Once an Xstart session is created, the remote X application can be executed by simply clicking it in Windows. 1. Run Xstart in Xmanager folder. Start 11

Fig. 8: xterm window Start 13

16 If you experience problems using Xstart, visit the customer support page in the following address: Most problems are caused by a firewall, user PC, or network settings. In some cases, users may have to consult with network or system administrators. Exit Xmanager To end a remote X application started by Xstart or Xbrowser, select [Close] from Xmanager system menu. For Xmanager system menu, see Window Mode. To Automatically Exit Xmanager when All Remote X Applications are closed: 1. Select [Properties] from Xmanager system menu. Profile Properties dialog box is displayed. 2. Select [Exit Xmanager when all connections are closed] from the [General] tab. 3. Xmanager is finished when all X application windows are closed. If [Exit Xmanager when all connections are closed] option is not selected, Xmanager becomes initialized when all remote X applications are finished and stands by for a new X application connection. 14 Start

17 Session Management Sessions have connection information to connect to a remote host. Users can designate different options and server profiles for each connection by creating a session. Session types are divided into automatic XDMCP session, static XDMCP session and Xstart session. Icon Session Type Description Automatic XDMCP Static XDMCP Xstart Xbrowser sends a broadcast message to local LAN and dynamically finds the hosts. To find another subnet host, enter host IP address in the Options dialog box. All automatic sessions use the same settings. To change session settings, right-click on a session, select [Save As] and save the session. Then, right-click on a newly created session and select [Properties]. In this case, the newly created session becomes a static XDMCP session. Static session is a session created by a user. Static session can be created by copying an automatic session or using New Session Wizard. If a remote host does not respond to an XDMCP request message, the icon is displayed dimly. Users can create shortcut, change settings for this session and send this session to another user through . Xbrowser creates and manages Xstart sessions. Additionally, users can also manage these sessions in Xstart. Xbrowser and Xstart share all Xstart session. By double-clicking Xstart session, users can conveniently run a remote X application in their Windows. Xstart session is useful when running remote X applications one by one. This session connects to a remote host, automatically executes a designated command, and opens an X application in user s Windows. XDMCP session is used to bring the GUI login screen and the entire remote host desktop environment. Xmanager supports all UNIX/Linux GUI desktop environments including CDE, KDE and GNOME. Error!

18 Xstart Session By creating an Xstart session, a remote host X application can be executed in a user s PC. Xstart automatically processes the remote host login process and executes remote X applications designated by a user. Users can create Xstart sessions using Xstart and Xbrowser programs. To Create a Session with Xstart: 1. Run Xstart in Xmanager Folder. 2. Click [New]. New Session dialog box is displayed. 3. Enter a new session name and click [OK]. 4. Enter the remote UNIX/Linux host name or IP address in [Host]. 5. Select one of the host supported protocols from [Protocol]. 6. Click [Setup] to set options by protocol, such as port or timeout. 7. Enter remote host user account in [User Name]. 8. To save user password in session, select [Authentication] as Password and click the [Setup] button on the right. Password Setup dialog box is displayed. 9. Enter a command to be executed in a remote host in [Command]. To run xterm, enter command as follows: /usr/bin/x11/xterm ls display $DISPLAY Press the button below the [Command] label, to see a list of generally used sample xterm commands registered by UNIX/Linux type. Select the xterm suited to UNIX/Linux to connect to or add/remove frequently used commands by opening Registered Commands dialog box. 10. Click [Save]. To Create a Session with Xbrowser: 1. Run Xbrowser in Xmanager Folder. 2. Point to [New] in the [File] menu and select [Xstart Session]. New Session Properties dialog box is displayed. 3. Enter [Session] name in [General] tab. 4. Enter the remote UNIX/Linux host name or IP address in [Host]. 5. Select one of the host supported protocols from [Protocol]. 11. Click [Setup] to set options by protocol, such as port or timeout. 6. Enter remote host user account in [User Name]. 7. Enter password to user account in [Password]. 8. Enter a command to be executed in a remote host in [Execution Command]. For example, enter command as follows to run xterm: /usr/bin/x11/xterm ls display $DISPLAY 9. Click [OK]. Users can also create Xstart session using New Session Wizard provided in Xbrowser. If the Xbrowser session category is set as Xstart, point to [New] in the [File] menu and select [New Session Wizard] to open it. 16 Error! Use the Home tab to apply 제목 1 to the text that you want to appear here.

19 To Create Shortcut to Xstart Session: 1. Run Xstart. 2. Select a session from [Session] list. 3. Click the arrow button to view more menus and click [Create Shortcut]. Browse For Folder dialog box is displayed. 4. Select a folder in which to create shortcut. Automatic XDMCP Session Xbrowser sends an XDMCP Broadcast message to local network or a network designated by a user and shows the hosts that respond to the message. These sessions are automatically created by Xbrowser and users do not need to create them by themselves. So, these sessions are called automatic sessions. In general, all UNIX/Linux systems support XDMCP service, and there should be no problem finding hosts in the Xbrowser window. In some cases, a remote host is set not to support XDMCP service and, as a result, it is not displayed in Xbrowser. In this case, contact the system administrator of the concerned host so that it supports XDMCP service. Xbrowser provides an option to find hosts in other networks. Additionally, it offers an option to turn off broadcast function in case there are too many hosts in local network. To Find Host in Another Network: 1. Run Xbrowser. 2. Select [Options] in the [Tools] menu. Options dialog box is displayed. 3. Enter the host name or IP address to find in [Search] section or enter network address to find all hosts available. 4. Click [Add]. 5. Click [OK]. To Turn off Local Broadcast Option: 1. Run Xbrowser. 2. Select [Options] in the [Tools] menu. Options dialog box is displayed. 3. Unselect [Search for local hosts (XDMCP Broadcast)]. 4. Click [OK]. If there are too many hosts in the user s local network and there are a limited number of hosts to use, it is convenient to turn off [Search for local hosts (XDMCP Broadcast)] option and add only the necessary host to the list of search addresses. Static XDMCP Session In addition to automatic session, Xbrowser provides static sessions, such as Passive, XDMCP Query, XDMCP Broadcast, XMDCP Indirect and Secure XDMCP. Unlike automatic sessions, static sessions are displayed in Xbrowser window at all times and can be created, modified, or deleted by users. To Create Passive Session: 1. Run Xbrowser. Error! Use the Home tab to apply 제목 1 to the text that you want to appear here. 17

20 2. Select XMDCP in the sessions category on the left. 3. Point to [New] in the [File] menu and select [New Session Wizard]. New Session Wizard is displayed. 4. Select None (Passive) in [Method] and click [Next]. 5. Select a server profile from [X Server Profile] and click [Next]. 6. Enter a session name in [Name]. 7. Click [Finish]. When a passive session is executed, Xmanager enters a mode to stand by for an X application connection. Then run a remote X application by using Xstart or a terminal program, such as telnet. To Create XDMCP Query/Broadcast/Indirect/Secure XDMCP Session: 1. Run Xbrowser. 2. Select XDMCP in sessions category. 3. Point to [New] in the [File] menu and select [New Session Wizard]. New Session Wizard is displayed. 4. Select XMDCP Query, XDMCP Broadcast, XDMCP Indirect or Secure XDMCP in [Method]. XDMCP Query connection is made directly with a designated host and GUI login screen can be brought to a user s window. XDMCP Broadcast connection is a method where Xmanager opens Chooser dialog box and lists hosts available for connection. XDMCP Indirect connection is similar to XMDCP Broadcast connection. However, Chooser dialog box is displayed by a remote host, not Xmanager. Secure XDMCP connection can be used when Xmanager is inside a firewall or a private network and a remote host is outside a firewall or a private network and thus users cannot make a direct XDMCP connection. If SSH server is in operation on this remote host, XDMCP connection with a remote host can be achieved using the SSH tunneling of Secure XDMCP connection. 5. Enter the remote host name or IP address in [Host] and click [Next]. 6. Select server profile from [X Server Profile] and click [Next]. 7. Enter a session name in [Name]. 8. Click [Finish]. To Create Shortcut to Static Session: 1. Run Xbrowser. 2. Right-click on a session. 3. Select [Create Shortcut]. To Send Session through 1. Run Xbrowser. 2. Right-click on a session. 18 Error! Use the Home tab to apply 제목 1 to the text that you want to appear here.

21 3. Point to [Send To] and select [ Recipient]. To Bring Session: 1. Drag a session from an external folder. 2. Drop it in Xbrowser window. Only static sessions saved in a file can be dragged and dropped. Automatic sessions cannot be brought in. To Share Session with Other Users: 1. Run Xbrowser. 2. Right-click on a session. 3. Select [Sharing]. This task requires administrative permissions. Shared sessions are moved to a shared folder. To Save Automatic Session as Static Session: 1. Run Xbrowser. 2. Select an automatic session and right-click on it. 3. Select [Save As]. Session Properties Setting A session has basic connection information, such as a host name and a port. In addition, you can configure XDMCP settings, a connection address, a server profile and a display number. To Change Session Connection Information: 1. Run Xbrowser. 2. Right-click on a session. 3. Select [Properties]. Session Properties dialog box is displayed. 4. Modify connection information in the [Connection] section of the [General] tab. For details about XDMCP session and Xstart session properties, see XDMCP Session Properties and Xstart Session Properties respectively. To Allocate a Display Number: 1. Start Xbrowser. 2. Right-click on a session. 3. Select [Properties]. Session Properties dialog box is displayed. 4. Click [X Server] tab. 5. Turn off [Allocate display number automatically]. 6. Enter a display number in [Display Number]. 7. Click [OK]. Error! Use the Home tab to apply 제목 1 to the text that you want to appear here. 19

22 In case display number is automatically allocated, each session holds an intrinsic display number starting from the default display number set in profile. When several Xmanager sessions are executed, each session gets a unique display number and it is displayed on the title bar of Xmanager such as [:0.0]. The first number is the display number and the second number is the screen number. In Xmanager, the screen number is always 0. Display number must be a value between 0 and 255. Xmanager obtains TCP port number by adding 6000 to a display number. If a user enters the number 10 in [Display Number], Xmanager communicates with X applications using TCP port Some UNIX servers cannot recognize a three-digit number. It is thus safe to use a number smaller than 100. To Designate a Specific Profile to Session: 1. Run Xbrowser. 2. Right-click on a session. 3. Select [Properties]. Session Properties dialog box is displayed. 4. Click [X Server] tab. 5. Select a profile from [Server Profile] list. 6. Click [OK]. XDMCP Session Properties The following are descriptions of connection-related items in the XDMCP Session Properties. The items are displayed in the [General] tab of XDMCP Session Properties dialog box. Method The session connection methods are None (Passive), XDMCP Query, XDMCP Broadcast, XDMCP Indirect and Secure XDMCP. For descriptions of each connection method, see Static XDMCP Session. Host Enter remote host name or IP address for connection. Check if a display manager is in operation in the remote host. Most UNIX/Linux use dtlogin, kdm, gdm, or xdm as the display manager. Port Number Enter remote display manager port number. The default value is UDP 177. Use Default Set port number as the UDP 177 default value. Local Address Select one of the user system IP addresses. This option is used only when user system has several IP addresses. If Auto Select is selected from the list, Xmanager finds an IP address appropriate for connection. If Xmanager fails to find an appropriate address, open IP Selector dialog box for a user to directly select an address. Display manager on a remote host will connect to the IP address selected by a user. If an inappropriate IP address is selected, display manager cannot connect to Xmanager and login screen cannot be displayed. Connection Address 20 Error! Use the Home tab to apply 제목 1 to the text that you want to appear here.

23 This option is necessary when you connect using port forwarding in a limited network environment such as firewall or proxy server and when automatic connection address does not function properly due to XDM server settings even if Secure XDMCP connection is selected. When your Windows resides in a private network with a firewall, Xmanager cannot get a remote login window with an XDMCP connection. It is because that the firewall blocks incoming connections and the remote display manager cannot reach at Xmanager on your Windows. To use this feature, you need to allocate a listening port in the firewall and forward incoming connections to your Windows. Address Type Select User Defined when using a proxy server or attempting XDMCP connection in an environment blocked by a firewall. In case of Secure XDMCP, if Automatic of connection address fails, select IP address of SSH server or Loopback Address ( ). IP Address If [Address Type] is selected as User Defined, enter proxy server or firewall server IP address. The remote display manager attempts connection using this address and the proxy server forwards the connection to the user s system. Port Number If [Address Type] is selected as User Defined, designate a TCP port number allocated to a proxy server and standing by for port forwarding. For example, let s assume that a user s computer uses , a private IP address, and firewall server uses , a private IP address. Additionally, the firewall uses xxx.10, a public IP address, for an external Internet connection, and the UNIX host IP address is xxx.100. In this case, you need to configure the firewall to forward incoming connections ( xxx.10, 6010) to Xmanager ( , 6010) on your Windows. This is called port forwarding. For this setting, make an inquiry to the firewall system administrator. Now, enter xxx.100 in the [Host] box of [Connection] field, and select User Defined as [Address Type] in [Connection Address]. Then, enter xxx.10 in [IP Address] and enter 6010 in [Port Number]. Click [X Server] tab, clear [Allocate display number automatically] option and enter 10 (TCP 6010) in [Display Number]. The [Connection Address] setting process when connecting with an external host through a router, is described in Connection with MIT Kerberos To authenticate with Kerberos using SSH, there are few things that needs to be set up beforehand. Xmanager 5 is tested with MIT Kerberos server version 5 and MIT Kerberos module for Windows. This article assumes that you have working Kerberos server and client. To create a new Kerberos session, 1. Open Xstart and click New. 2. Enter a host name in Host. 3. Select SSH from Protocols list. 4. For Authentication, select Kerberos (MIT Kerberos GSSAPI.dll). Error! Use the Home tab to apply 제목 1 to the text that you want to appear here. 21

24 5. Enter the user name. 6. Click Save to save. 7. Select the session file you just created and click Run. You have finished creating a session that will use the MIT kerberos module. When this session opens, it will try to use the Kerberos credential for the specified user. It has to be the same user you defined in the Network Identity Manager. Firewall-related Setting. Xstart Session Properties The following are descriptions of connection-related items in Xstart session properties. The items are displayed in the [General] tab of Xstart session properties dialog box. Host Enter the remote UNIX/Linux host name or IP address. It is faster and more stable to enter an IP address than a host name, because Xstart does not have to connect to a name server. Protocol Select a protocol for remote host connection. Xstart supports SSH, TELNET, RSH, REXEC, RLOGIN and LOCAL protocols. Before selecting a protocol, be sure to check whether or not the remote host supports the protocol. SSH is a protocol for secure connection with remote host. SSH provides Public Key User Authentication, powerful data encryption and X11 forwarding functions. Using SSH protocol, a remote X application can be executed securely using the powerful encryption, even in a network environment vulnerable to security. Additionally, SSH helps you with convenient connection to a host located on the other side of a firewall. A user on a private network can thus run an X application on another network using X11 forwarding function. TELNET is a legacy protocol for using a remote terminal. It is supported by most servers, such as UNIX, Linux and VMS. RSH is a simple protocol for connecting with a remote host and running a designated command. It does not require a password and be careful in using it for security. REXEC is a protocol for running a command in a remote host. Although the functions are almost similar to those of RSH, REXEC requires a password for connection. RLOGIN is a simple program for connecting with a remote host and obtaining login shells. Although similar to TELNET, RLOGIN authenticates users in a similar method to RSH. LOCAL is for running an X application installed in a user s PC, not a remote host. For RSH, REXEC and RLOGIN, the latest UNIX/Linux versions do not permit connection with the default configurations. Setup Open the Protocol Setup dialog box in relation to the protocol selected and set connection port, timeout and options by protocol. User Name Enter remote host user account. Execution Command 22 Error! Use the Home tab to apply 제목 1 to the text that you want to appear here.

25 Enter a command to be executed in a remote host. For example, if a user executes xterm, the execution command is as follows: /usr/bin/x11/xterm display $DISPLAY The $DISPLAY variable is converted to an appropriate value by Xstart. In general, it is converted to :0.0 when the IP address of your Windows is To designate the value directly, the following command is executed: /usr/bin/x11/xterm display :0.0 Additionally, $PCADDR variable and $DISPNO variable can be converted. In this case, the execution command is as follows. /usr/bin/x11/xterm display $PCADDR:$DISPNO If a user s PC uses several IP addresses, Xstart automatically changes them to appropriate values. Registered Command (Direction Key Button) Click this button to select a predefined command on a menu. By selecting a command on the menu, you can enter a long command just with a single click. Select [Add/Remove] to display Registered Commands dialog box. In the dialog box, register the frequently used commands. Show connection status window Select this option to check connection status or messages transferred from a remote host. This option is useful when Xstart fails to run an X application. SSH Protocol Setting Set the following SSH-related options for an Xstart session or a Secure XDMCP session for which SSH protocol is selected. To set an SSH protocol, designate protocol as SSH in the Xstart Session Properties [General] tab and click [Setup]. Alternatively, designate method as Secure XDMCP in the XDMCP Session Properties [General] tab and click [Setup]. The SSH server host is different from the XDMCP server Secure XDMCP is a connection method that X clients connects to Xmanager of PC through SSH tunneling. If SSH server is not running on XDM host server, a proxy server for SSH tunneling is required. This option is to configure this SSH proxy server. Host Enter host name or IP address of the proxy server for SSH tunneling. In this case, you need to configure SSH proxy server so that it can bind to not only loopback address ( ) but also external connections. Preferred Version Select an SSH protocol version to use. SSH2 is recommended since it provides better security and more functionalities than SSH1. Port Number Enter port number to use in SSH connection. Use Default Error! Use the Home tab to apply 제목 1 to the text that you want to appear here. 23

26 Set [Port Number] as 22, the SSH protocol default port. Send keep alive signal Send keep alive signal to a remote host. This function is used to prevent disconnection while a user is temporarily absent. In some network environments, a gateway or a firewall system may terminate connections without notice when the connection is idle for a specified period of time. Encryption Encryption algorithms are used to encrypt and decrypt network traffics. Users can select their preferred algorithms from the list. If <Cipher List> is selected, several algorithms can be tried in order of preference. To modify <Cipher List>, click [Edit]. MAC MAC(Message Authentication Code) ensures that data transferred through a network is not changed by a third person. It provides increased security of SSH2 protocol over SSH1. Users can select their preferred MAC algorithms from a list. If <MAC List> is selected, several algorithms can be tried in order of preference. To modify <MAC List>, click [Edit]. Compress network data(using ZLIB compression) Select this option to compress all data traffic with the ZLIB algorithm. Compression will provide better performance in a slow network environment. Allocate a terminal before executing the command This option is selected when you want to allocate a virtual terminal on the remote host and then run a command on the terminal. Virtual terminals are required by several X applications. When virtual terminals are allocated, shell environment variables are set as per the general login envirorment. TCP/IP Forwarding In [Tunneling] tab, you can list, add and delete TCP/ IP forwarding channels in a session. Xbrowser Window Setting Xbrowser is similar to Explorer and consists of menus, standard buttons, an address bar, workspace and a status bar.

35 gateway or there is a firewall in between user s PC and a remote host because Xmanager is a server program and remote X applications connect to Xmanager in a user s PC. The keep alive option to retain connection, which is supported by SSH protocols, is useful when a firewall forcefully ends a connection that is idle for a set period of time. Port-forwarding is required for XDMCP connections when you are in a private network and you connect to a remote host over a router. Once you have configured port-forwarding on the router, you should configure connection address for XDMCP connections. To Use Keep Alive Option for SSH Connection in Firewall Environment: 1. Run Xstart. 2. Select a session from the [Session] list. 3. Select SSH from the [Protocol] list. 4. Click [Setup]. SSH Protocol Setup dialog box is displayed. 5. Click the [General] tab. 6. Select [Send keep alive signal]. 7. Click [OK]. To Set Router Port Forwarding: 1. Connect to a router and move to port forwarding setup page. 2. Forward external router ports TCP 6000 ~ 6010 to the 6000 ~ 6010 ports in the user PC. If the user PC IP address is : Router Port PC Port Address Router port number does not need to be the same as PC port number. However, X applications attempt connection with the IP address and the corresponding router port. Since router forwards packets to a PC port according to the port forwarding rules, the display number designated in Xmanager sessions files must be the same as the port designated in router port forwarding rules. Xmanager display number added with 6000 becomes the port number. 3. Save settings. 4. In Xstart session, values relating to display options must be designated as display numbers relevant to the router IP address and port number of the PC designated in the router port forwarding setting. For XDMCP session, [Connection Address] must be set. For port forwarding setting, see router manual. To Set XDMCP Session Connection Address: 1. Run Xbrowser. 2. Right-click on a session for which to set connection address. 3. Select [Properties]. 4. Click the [General] tab. 5. Select User Defined as [Address Type] in the [Connection Address] field. 6.

38 Xrcmd Command Line Options Xstart provides command line option, which enables advanced users to integrate the program with their applications. In reality, Xstart only provides a user interface for sessions creation and management. When a user opens a session using Xstart, it executes Xrcmd.exe command and forwards the session information. For direct connection, Xrcmd.exe, must therefore be used, not Xstart. Xrcmd is found in a folder where Xmanager is installed. The Xrcmd Command Line Rules are As Follows: Xrcmd protocol ssh telnet rexec rsh rlogin local host hostname [ user username] [-password password] [-userkey keyname] [-passphrase userkeypass] [-shell] [-zlib] [-status] [-result] [-dispno nnn] [-timeout nnn] [-port nnn] -command remote_command : command option must be at the end. Options: Tag -protocol protocol -host hostname -user username -password xxxx -userkey keyname -passphrase userkeypass -shell -zlib -status, -result -dispno nnn -timeout nnn -port nnn -command command Description Designate a connection protocol. Designate a remote host. Designate remote host user account. Designate user account password. Designate user key name. This option is used only for SSH connection. Enter user key passphrase. This option is used only for SSH connection. Run a command after shell (terminal) starts. This option is applied only to SSH connection. Compress network data using zlib algorithm. This option is applied only to SSH connection. Show Remote execution result window. Designate a display number to be used by Xmanager. If this option is not set, Xmanager automatically allocates an appropriate value. Close connection after nnn seconds. Designate connection protocol port number. If this option is not set, the default protocol port number is used. Designate a command to be executed in a remote host. Ex.: Xrcmd protocol telnet host mylinux user myname status command /usr/bin/x11/xterm ls Xrcmd connects to mylinux using a telnet protocol and logs in with myname. Then, it executes xterm command on a remote host. Connection status can be checked through Remote execution result window during the course of connection. 36 Error!
